The passage around this formula
…disagree not by a fixed offset but by a time-dependent, oscillating quantity, largest exactly where a wavepacket carries significant negative-energy content, a regime the nonrelativistic limit removes entirely. As v c and the wavepacket is restricted to the positive-energy subspace, the oscillating term’s amplitude falls relative to the packet’s own spatial width, and , , and converge onto one description — the same nonrelativistic recovery checked twice…
